White Mississippi Teens May Have Attacked Homeless Blacks In Jackson

The white Mississippi teens caught on surveillance video beating a black man, then killing him by running him over with a pickup truck may be responsible for other attacks on homeless black men in the area, the head of the state's NAACP told ABCNews.com.

James Anderson, an auto worker, was killed June 26 in Jackson, Miss. His murder received renewed attention when the grisly surveillance video surfaced this week.

The video allegedly shows Deryl Dedmon, 18, and several of his friends beating Anderson, and then driving over his body. Dedmon, who is accused of driving the pickup truck that lurched over Anderson's body in the video, is in jail on $800,000 bond awaiting a grand jury investigation into Anderson's homicide.

Dedmon's friend, John Rice, who was at the scene during the beating, had originally been charged with murder. But during a preliminary hearing detectives testified Rice, who is also 18, left the parking lot before Anderson got run over.

Rice's charge was lowered to simple assault and will be sent to the grand jury along with Dedmon's. In the meantime, Rice was released on $5,000 bail.

The teens charged have not yet entered a plea. Neither Dedmon nor Rice's lawyer returned a call from ABCNews.com.

Prosecutors are trying to determine if the other teens involved in the incident should also be charged.

The attack on Anderson may have been the latest assault on blacks in the area, Derrick Johnson, president of the Mississippi NAACP, told ABCNews.com. He said evidence indicates the white teenagers deliberately "set out to go and mess with African Americans."

Johnson said that sources who wished to remain anonymous said the teens "had, as a practice, targeted African Americans in the city of Jackson who were homeless." He's now working to verify the legitimacy of those claims.

Jackson police spokeswoman Colendula Green said detectives had received a call from "one person" saying that "white people" were beating up on homeless African Americans. They looked into it, she said, and couldn't substantiate the claims.

For now, she said, "it's hearsay," and the alleged incident reported to police happened "three or four years ago."

Video: Teens Run Over James Anderson

The surveillance video shows Anderson, 49, in the parking lot of the Metro Inn in Jackson. A group of white teens who had driven in from adjacent Rankin County in a white SUV and green pickup truck, descend on Anderson, beating him, walking back and forth between him and their cars. One can be seen pumping his fist in the air.

Anderson, who appears to be stumbling toward the street on the curb, disappears underneath Dedmon's car. Dedmon and his two teenage female passengers –- who were not charged -- then allegedly drove to a McDonalds to meet up with their friends.

"I ran that n****r over," Dedmon reportedly said in a phone conversation to the teens in the other car.

Metro Inn general manager Val Patel told ABC News affiliate WAPT Dedmon, "rolled the window down and laughed and danced" and took off toward the interstate.

Anderson was pronounced dead at a hospital.

"We're all shocked by the allegations. It's uncomfortable, I'm sure, for all of us to know this can happen to a random citizen," Hinds County District Attorney Robert Schuler Smith said. "There were racial slurs used throughout the turn of events which led to the conclusion that it was most likely a hate crime."
